10 Claims.

This invention relates to covering for laying upon a surface and more especially upon the surface of walls to simulate a structure of masonry.

5 The invention relates more particularly to a covering sheet having its surface to be exposed so made as to simulate a plurality of courses of masonry and of a form for laying in complementary relation to other covering .sheets upon the surface.

Coverings having for their purpose the simulation of masonry structures heretofore have been proposed in various forms, including strips and sheets upon the surface of which the simulation of the masonry joints has been applied, such as by printing contrasting stripes upon the sheet or by embossing grooves in a plastic covering upon the surface of the sheet. Simulations of brickwork construction have been attempted by using 6 shingles or shingle strips in which a cutout or notch has been used to simulate the vertical joint of the brickwork without particular means upon the strip for sharp demarcation of the horizontal;

joint or the brickwork. The method of printing is unsatisfactory owing to the lack of characteristic appearance of the joints, especially the vertical joints, and the method of embossing the channels in the'coating involves the use of expensive embossing rolls. In the constructions in which the simulation of the horizontal joint of brickwork has not been provided a characteristic simulation of the brickwork construction also is not obtained. Moreover, when a plurality of courses of masonry is simulated upon the sheet the problem of suitably forming the joints between adjacent sheets to make said joints inconspicuous has not been solved heretofore.

'It is an object of the present invention to provide a covering sheet which may be easily formed so as to simulate a plurality of courses of masonry and which will not require expensive machinery but may be manufactured with the ordinary machinery used for the production of covering materials'such as roofing.

It is also an object of the invention to provide such a covering unit with a sharp demarcation of the longitudinal as well as the transverse joints of masonry, whether of brickwork or other type 'of construction, without the necessity of manu-' facturing the unit by expensive methods.

It is a further object of the invention so to form '1 the covering sheets that they may be laid adjacent each other in complementary relation with the joints between the sheets inconspicuous and without marring the appearance of the masonry simulating areas.

Other objects or the invention will appear from the following description.

The invention provides a covering'sheet upon 5 which are simulated the masonry units separated by longitudinal stripes of contrasting shade or color for the simulation of the longitudinal joints. Said stripes simulating the longitudinal joints are continuous longitudinally of the covering and 10 separate discontinuous longitudinally extending areas which .provide the simulation of the masonry units. when simulating brickwork constructions, said discontinuous longitudinally extending areas substantially form discontinuous 15 horizontal and parallel vertically spaced stripes of similar shade and color, said discontinuous stripes.being vertically spaced by the continuous stripes contrasting therewith and simulating the horizontal joints or mortar lines of the brick- 20 work construction.

In order to provide the .discontinuous stripes according to my invention I form notches or cutouts through the material of the sheet, that is,

the base upon which the simulation of the 25 masonry structure is made. These notches or cutouts extend transversely to the longitudinal continuous stripes and separate the simulated masonry units. In the simulation of a construction such as brickwork in which the vertical joints of the brickwork are in staggered relation in successive courses of brick, said transverse notches or cutouts extend between longitudinal continuous stripes. Thus the areas simulating. the masonry units or the bricks are demarked by the 35 longitudinal continuous stripes and the transverse notches or cutouts.

While I may provide the simulation of the longitudinal stripe by any convenient method,

including printing or embossing, I prefer 'to 40 "the' simulation' of masonry upon the surface of roofing materials, particularly roofing materials having a coating of asphalt upon abase sheet, upon which asphalt coating may be applied a mineral surfacing material, I able'to obtain the sharp' gdemarcation while at the sametime providing a; characterof surface upon said IOU-8 55 tudinal scraped stripe which serves to simulate the character of the masonry :loint. This is especially true when the simulation of masonry ,set up in black mortar is desired, since the sur 5 face presented by the scraped asphalt is of such a character as suitably to simulate said mortar. By using a cutout through the base sheet for the simulation of the transverse or vertical joints of the masonry, I secure a sharply demarked outline for the masonry units and I am able, by'the ordinary methods of cutting notches in covering materials such! as are practiced in the roofing art, in a single operation or in consecutive operations without special handling, to form the simulation of the longitudinal joints and of the transverse joints as explained above. Such methods may be practiced by providing a cutting roll or other usual cutting device in cutting the sheet,

as described in said patent to Outman, which roll will form the notches in proper relation to the stripes.

Thus I may produce a sheet which provides the simulation of a plurality of courses of masonry and the simulation of the joints of mortar in '2 which the masonry units are laid. The simulation of the transverse Joints of the masonry lying betweenmasonry units which areadjacent the edges of the sheet may be provided by notches of suitable width extending from the edge of the sheet to meet the simulated longitudinal joints nearest to said edges. The simulated transverse joints between units lying in intermediate courses of the masonry may be provided by cutouts of suitable width between the simulated masonry units in the intermediate courses and extending between the simulated longitudinal joints adjacent said courses. T'By utilizing said notches and cutouts not onlyis a sharp demarcation of the transverse Joint'pro- 40 vided, but the transverse joint may be given the proper appearance by providing upon the surface which is to be seen through the cutout or notch a surfacing material of; a characteristicwhich will simulate that of the mortar in masonry Joints. 7 1

My invention also provides in a covering of the type above described a form of the sheets such that when'laid upon the surface in-complementary relation to each other the simulation of the masonry or of the brickwork may be carried.

out over the surface to be covered. In order to accomplish this purpose, I so form the edge of the sheet that said edge is cut substantially along the simulated joints of the masonry. Thus I am able to avoid cutting across the area of simulated masonry units and, moreover, by confining the cut edges of the sheet to the simulated Joints, the joint between sheets laid upon the surface'becomes inconspicuous whereas when the sheet is cut along a straight line or a line of considerable extent in any direction as in coverings heretofore proposed, particularly if said line crosses a simulated masonry unit, the joint between-the-sheets becomes difllcult, if not impossible,to conceal and the proper simulation of the masonry structure is not obtained. The sheet made by cutting along the simulated masonry. joints in most cases acquires an offset or a stepped ".form as may be seen in the drawing. The invention is illustrated in the drawingin the particular embodiment showing a brickwork construction. r

In said drawing Figure 1 is a face view of the covering sheet;

Figure 2: shows a modified form of the invention in-the complementary arrangement; and

Figure 3 is a cross section on line 33 of Figure 1 or 2.

In Figure 1 is shown a sheet I having thereon 5 continuous stripes 2 extending lengthwise of the sheet, said stripes being spaced apart andbeing spaced from the edges of the sheet distances f suitable to simulate the spaced longitudinal Joints of masonry. Between said continuous stripes 10 simulating the longitudinal Joints are dlscontinuous stripes of contrasting color or shade providing the areas 3 for simulation of the bricks. Said areas 3 are separated by the transverse notches I or transverse cutouts 5. 15

As stated above, I" may form the horizontal joints of the brickwork as shown in Figure l by scraping the stripes 2 in the asphalt coating upon a roofing sheet, the stripes 2 then having a surface character similar to black mortar. The 20 areas 3 between said continuous stripes 2 may be coated with mineral surfacing material such as granular slate represented in Figure 3 by the numeral 6, the asphalt coating being there shown at 1. Thus the surface of the areas 3 may be 25 given a character similar to that of the surface of brick and contrasting with thestripes 2. The vertical joints of the brickwork are simulated by the notches l or the cutouts 5 and sharply demark the areas 3 and contrast therewith. Said con- 30 trast may be provided merely by the cutout by which issecured a shadow eflect as well as the sharp demarcation provided by the cut material, or-the surface upon which the covering of my invention is laid may be given a suitable character 35 so that said surface may be seen through the cutouts and ma {simulate the mortar of said transverse Joints. 5

In Figure 1: there is shown also the stepped form of the covering of my invention. It will ,be 40 noted that the right hand edge of the sheet has been out along the Joints of the masonry, i. e., along both the Evertical and the horizontal Joints.

It will be clear that such a form of stepped edge may be provided by cutting a continuous sheet 5 in the lines lll'textending generally along the longitudinal Joints 2 and connecting cutouts l, p or 5. a In the particular form illustrated said lines j Ill slope along the longitudinal stripe 2 between courses of the offset bricks. Thus, such a sheet K5 may be severed into two parts one having the 5.,- form of Figure 1 and the other a form complementary thereto. Said stepped edges on the two sheetswill be complementary and will. fit together when laid upon a surface. i

In Figure 2 is shown an assembly of two units of complementary shape having the end edges cut instaggered or oifset form. From the figure it may be seen that said edges are out along the simulated longitudinal Joints 2 and connecting the staggered or offset'vertical Joints I and I,

thus similarly to the form shown in Figure l providing the feature of the invention by which the edges of the sheet are made without cuts across the area simulating the masonry. joints, that is, '5 a they are made within the lines of the simulated masonry Joints. The forms of edges. shown in Figures 1 and 2 are illustrative of the invention, but the invention is not limited to the particular forms there shown. 0

The cuts along the longitudinal joints 2, without departing from the invention, may be made along other lines than along the sloping lines at III as. shown in the figures. Within the scope of my invention however, I provide the offset or stepped 7'5 forming the horizontal stripes nor of cutting the form by cutting along any lines lying within the simulated longitudinal and vertical joints.

The invention is not limited to a particular kind of sheet material nor to particular methods of transverse notches and cutouts. However, in my invention I use a continuous longitudinal stripe separating discontinuous stripes or areas of contrasting color, which discontinuous areas provide the simulation of the masonry units because of the separation obtained by the notches or cutouts. I further provide the stepped form of: the edge of the covering by so cutting a sheet alone the simulated longitudinal and transverse joints that complementary edges upon two sheets may be obtained for laying in complementary relation upon. a surface to provide full coverage thereof without conspicuous joints between adjacent covering sheets and without waste of the material of the sheet except that removed in forming the cutouts.
